The article describes a method of solving the problem of designing the friction surfaces withcomposite coatings. Despite the fact that many scientists have investigated the effect of coatings on theproperties of the items during the exploitation, however, has not yet been carried out a detailed study ofelastoplastic properties of the coating to the copper-containing material with different concentrations ofultrafine additions of copper, nickel, molybdenum disulfide. Elastoplastic properties of such materials isusually described by the relations of the deformation theory of plasticity.It is proved that the modeling of physical and mechanical properties, and varying the coatingcomposition can achieve a favorable combination of properties of the surface and the substrate. Proposed ofdesigning friction surface with composite coating, development an adequate model of the interaction ofsurfaces, which makes it possible to judge which components need to enter into the coating to obtain thedesired properties.

NiCr-Cr3C2-Ni/MoS2composite coating was prepared by supersonic plasma spraying (S-PS) process. The tribological properties of the composite coating at 25°C, 300°C, 500°Cand 750°C were studied. The wear mechanism for the coating was discussed considering the microstructures, compositions and mechanical properties of the composite materials. Results show that the coating exhibits good tribological properties at 750°C, which was attributed to the compact and continuous Cr3O2transfer film formed on the friction surface. The wear rate of the coating increases with the temperature increase, which was associated with the decrease of the mechanical strength and stress-resistance of the coatings.

The features of the tribomodification process of friction surfaces of steel 40Kh with modified vermiculite are studied. The mechanism for forming of ceramic-metal coating is refined, the chemical composition and mechanical properties of the coating are determined. It is found that ceramic-metal layer 6.0...7.5 μm thickness is formed on the friction surface, which contains large amount of carbon, silicon, oxygen and minimum amount of iron (only 8...9 %). The alloying depth of the surface layer with elements that make up the modified vermiculite reaches 0.25 mm

Thermoplastic Properties

Thermoplastic elastomers (TPEs) have elastic properties that are similar to rubber but capable of melting and all thermoplastic properties. Block copolymers are also widely used, in which there are links of different polymers in the structure of their macromolecules. So styrene-ethylene-butylene- styrene (SEBS) belongs to the second generation, the products of which have high physical and mechanical properties, and biocompatibility allows it to be used in the medical field. The main characteristics and analysis of advantages of TPE on the example of SBSS in comparison with traditional materials are presented in the paper.
